题型:阅读理解

My daughter Alisa was born blind in her right eye and was bullied (欺侮) pretty severely in school. So I quitted my job as a babysitter and then schooled my daughter heart and soul at home.

A year ago a boy of 14 befriended my daughter on Facebook after reading something Alisa wrote about bullying. Today he messaged her and asked if she would like six tickets to a Colorado Rockies baseball game. They have never met in person but she said, “Sure! That would be great.”

Then I received a call from his mother explaining why her son had chosen my daughter. She said he thought my daughter deserved them because of all the good she does in the community. Her son, she explained, had experienced a similar situation and was also home schooled.

What she said is true. Now my daughter Alisa continues to teach groups of girls in trouble in our community how to look within themselves for the positive and how to be their own person.

Everything taken into consideration, we decided to meet the mother and the boy at a local bike shop. After meeting, the boy approached my car and my daughter gave him a hug and thanked him for his generosity. She told him that she had never been to a baseball game and that she was going to take her entire family, including myself, her dad, little sister, her cousin and an aunt who has brain cancer.

We all thanked one another, got in our car, and went our way. As we drove home my daughter opened the envelope. Inside it were the tickets and $100 each to buy hot dogs, pay for parking and not have any worries but a great time.

My daughter has always been the giver and now she and our family are the receivers and I can not tell you how incredibly honored we feel to be on the other end. What an incredible young man to have such a kind idea.
